Abstract (en)
In a liquid crystal display device according to the present invention, when the polarities of the source signal voltages do not change over a plurality of horizontal scanning periods, the image write pulse of the gate signal supplied to a gate bus line that corresponds to pixels along the j th row rises before the source signal voltages change to values that correspond to pixels along the j th row. Next, the image write pulse of the gate signal supplied to a gate bus line that corresponds to pixels along the j th row falls, and then the image write pulse of the gate signal supplied to a gate bus line that corresponds to pixels along the k th row (j‰ k) rises. The polarities of the storage capacitor signal voltages applied to storage capacitor bus lines that correspond to sub-pixels of pixels along the j th row are inverted after the image write pulse of the gate signal supplied to a gate bus line that corresponds to pixels along the k th row rises.
